A suggestion. Multiple AGM batteries where you propose to put your batteries next to your CONverter. That way, nothing corrodes including your converter.
Three Lifeline batteries can accept a 300 amp charge when starting out.
So your existing charger is as worthwhile as having a garden hose in a forest fire. Even 3 regular batteries can accept 100+ amperes.
Unless you like hearing your generator run.
Now here is a BARB directed at some folks (heh heh heh)
A good AGM can be discharged to a level of 30% remaining charge and not be damaged anywhere near as much as a flooded battery (cycle life degradation). Weight and space-wise this can be a deal maker.
Sell the battery on the tongue. Reduce weight. Having it there is a stupid design flaw, weight wise. Placing batteries opposite heavy appliances near the axles is the best distribution objective.
An EIGHTY to ONE HUNDRED ampere charger will reduce generator run time. Dramatically. As in, it's either that or three dollar + gallon gasoline and ear plugs and plan on seeing the local gas station, often.
